This is quite the change from a year ago, when the Golden Eagles relied on outgunning opponents from beyond the 3-point arc to win games. This year, Marquette (8-2) has been at its best when playing solid defense, especially at home.

Ethan Happ had 34 points on 16-of-21 shooting, along with 11 rebounds for the Badgers. But there were just 10 of 21 (48 percent) and 5 of 24 from the 3-point arc (21 percent).

"We knew if we took away the 3s that we were going to have a good chance to win the game," Sam Hauser said.

Tighter defense and a decided edge at the foul line boosted Marquette at the end.

The Golden Eagles were 22 of 34 from the charity stripe, with Howard going 12 of 15. Howard and Sacar Anim each missed twice at the line in the final 30 seconds to give Wisconsin (8-2) extra chances.

But Happ was called for an over-the-back foul at the other end with 9.2 seconds left. Ed Morrow's two free throws gave Marquette a six-point lead to finally ice the game.

It made for a thrilling finish in the rivalry's first game at Fiserv Forum, Marquette's new downtown home.

"Effort was there, but I think we've got to continue to improve at some of the intangibles and some of the things that are controllable," Wisconsin coach Greg Gard said.

Marquette beat a team ranked 12th in the AP Top 25 for the second straight week, having defeated Kansas State the previous week.

Wisconsin: The Badgers couldn't balance Happ's inside presence with outside shooting, which had been a strength this season. They were 1 of 12 from behind the arc after halftime. D'Mitrik Trice, who finished with 10 points, was just 1 of 6 from 3-point range.

"Trice is a huge key," Wojciechowski said. "Happ has been consistently terrific. When they're down, the guy who usually saves them on the perimeter is Trice."

Marquette: The Badgers broke through Marquette's defensive wall early in the game, but had trouble getting off good shots late. The presence of 6-foot-9 Theo John late, after he was mired by foul trouble, helped in the lane against Happ, a preseason All-American. Morrow, a post player who transferred from Nebraska, also converted an offensive rebound with 2:07 left for a 69-65 lead.

FOULED UP

Wisconsin, which was shooting 70 percent from the foul line this season, was off-target all afternoon, including just 9 of 21 on free throws after halftime. Brad Davison, a 90-percent free-throw shooter, was 0 for 3.

"We did too many things ... that shot ourselves in the foot," Happ said. "We're not happy about that."

LITTLE JOEY

The younger Hauser, a highly-touted recruit, scored four in the opening two minutes of overtime, including both free throws after Davison was called for a flagrant foul with 3:35 left. He also went 3 of 5 from 3-point range and played 33 minutes.

"Sam is about winning. He's about winning. He's about winning," Wojciechowski said, referring to Hauser. "His younger brother is really starting to find his footing."
